Flight cancellations piled up and state officials warned of continuing dangerous roads Saturday in the wake of a winter storm that closed schools and disrupted travel across parts of the southern U.S.

Portions of east central, north central, northwest, and south central Kentucky are under a winter storm watch from late Thursday through late Friday night, according to the weather service. Anywhere from 4 to 5 inches of snow are expected to fall, though higher amounts are possible.
